How smart is /bant/? Help a brotha out. Factor out the X. Theres supposed to be 2 values for x in this one.

>>

15

>>

potato

>>

>>2202327

(3±√-3)/2

the plus minus sign denotes that it has 2 values

Praise the mathematical prowess of the Nipponese.

But square root of a negative number doesnt exidt

>>2202354

Nigger if that's right you missed one. Three degrees means three roots

Do it again but better

Bretty gud but i need solutions

>>

>>2202327

IDK i'm seeing three values for x

>>

>>2202327

>cubic function

>should only be two solutions

Nice one faggot.

>>

>>2202471

two real solutions are possible anon

>>

s.s. {0,3}

>>

The problem is to solve the length of curve from that positive x value to the other positive x value. And i cant do that without knowing the value of the two points intersectinv the positive x axis

>>

I don't know who gave you that function but as far as manual exercises go that's actually a pretty shitty one. You can fill these values into the original and see it ends up to zero

>>

>>2202671

Ugh hold on I'll get a better quality

My prof is shit then. Dammit

Wrong

>>2202327

Do your own homework.

Don't factor out x, that work work better if you had a y value here,

Use synthetic division for a sure answer till you find enough zeros of the poly to got to a quadratic. It will be something like (x-r)(x^2-bx+c)

It doesn't look like you can do any x^2=m subsisting tricky here

Not easy stuff, what class is this? Are you sure you don't have a sign wrong?

>>

>>2202979

Stupid captia ate my image, this is one of 3 answers.

>>2202725

Zeros can be repeated, as "at most"

Just calculus. Calculating the length of the arc. My teacher probably wrote the question wrong i dunno

>>

x = the crippling realization that OP should do his own fucking Algebra II homework

>>

>>2202327

Are you supposed to find the derivative first?

>>

x^3 -3x^2 + 3

(ax^2 + bx + c)*(px+q)

x^3 * ap + x^2 * (aq + bp) + x^1 * (bq + cp) + x^0 * cq

ap = 1

cq = 3

aq + bp = -3

bq + cp = 0

a=1/p

(1/p)*q + bp = -3

b = -cp/q

(1/p)*q + (-cp/q)p = -3

c=3/q

(1/p)*q + (-(3/q)p/q)p = -3

(3p^3 - q^3) / (p*q^2) = 3

If you assume integer factors, p can be either 1 or -1 (because ap = 1). Regardless of which one you pick, it's obvious from the equation that you're not going to get any integer solutions. Conclusion: just use the closed form solution. Trying to factor it manually is not going to work.

At least you plugged it into something less common.

>>

>>2203068

Yeah like ur mum ayyyyy lmao

>>2203062

Thanks for the help anon but the test was like 5 hrs ago. I couldnt leave it alone so i had to look for answers even after the test. I dunno the teacher usually gives us doable problems. That one was unexpected

>>

>>2203038

Fuck u capitalist pig im looking for manually answering it by hand and apparently its not possible i had to use a calculator.

>>

>>2203105

>and apparently its not possible

But it is possible to solve by hand

www.encyclopediaofmath.org/index.php/Cardano_formula

Just not by manually trying to factor it.

>>

>>2203116

Nobody actully uses the formulas for anything above degree^2

>>2203231

Fun fact the formulas only exist up to degree 4 anyways because math

>>

>x^3

>two solutions

>>

>>2203284

But x^3=0 has only one solution.

>>

>>2202327

0=x^3-3x^2+3

0=3x^2-6x

X=(6+-√(-6)^2-4×3×0):2

X=(6+-6):2

X=0 or x=6

Dumb nigger
